Title: Improvements in or relating to valve gears for internal combustion engines
IPC: F01L1/22
Filed: 1957-05-28
Abstract: 805,729. Valve gear; lubricating. GENERAL MOTORS CORPORATION. May 28, 1957 [May 28, 1956], No. 16879/57. Classes 7(2) and 7(6) A valve rocker 7 is pivoted on an adjustable fulcrum 12 which incorporates a clearance adjusting mechanism comprising a screw-and-nut arrangement 14, 16, which are screwed apart by a torsion spring 21 to take up clearance. The pivot 12 is fixed in the cylinder head and passes through an aperture 11 in the rocker which has a spherical depression 20 engaging a corresponding head on the nut 16 which screws loosely on to the nut 15 fixed to the top of the pivot 12. During opening of the valve the movement of the rocker 7 causes slight rocking of the nut 16, due to the loose fit of the threads 17, which produces slight upward movement of the nut 16, allowing for expansion of the valve gear. Any clearance in the valve gear is taken up by screwing of the nut 16 towards the cylinder head by the spring 21 which is anchored at opposite ends 22, 23, in the nut 16 and screw 14. Lubricating oil is supplied through a bore 27 in pivot 12 and passages 28, 24, 25, to the threads 17. In a modification the spring is antchored to the screw and nut 14, 16, by fitting the end coils tightly into recesses therein and in a further modification the spring 21 is positioned between the outer end of the nut 16 and the head of screw 14.

Abstract: 616,183. Electric buzzers. VENNER TIME SWITCHES, Ltd., and HORGAN, W. F. June 5, 1946, No. 17118. [Class 13] [Also in Groups XVIII and XXXV] An alternating current buzzer comprises a coil and an associated iron core divided transversely of the direction of the flux therein into at least two relatively movable parts which vibrate against each other when the coil is energized.

Title: Improvement in method of operating a water gas generator
IPC: C10J3/00
Filed: 1929-06-07
Abstract: 336,203. Brassert & Co., H. A., and Western Gas Construction Co., (Assignees of Chapman, W. B., Andrews, C. W., and Young, H. B.). Nov. 27, 1928, [Convention date]. Producers.-In a water gas generator having mechanical means for continuously removing ash from the fuel bed, the air-steam ratio is such as to maintain a zone in which the ash is liquefied and a cooler zone below this in which the ash tends to solidify and is removed by the mechanical device. The extent of these zones is controlled by increasing the down steaming so that, for example, the ratio of down steaming to up steaming is as 72 to 28. By this means the maximum temperature zone is lowered to close to the ash removing device. Thus by decreasing the up steaming, the air-steam ratio is increased, and the ratio of down steaming to up steaming is increased. A generator suitable for the purpose has a fixed grate 2 above which rotates a hollow water cooled beam 3, which is connected to an ash pan 7, and is preferably rotated intermittently at one revolution in about 50 minutes. A crushing ring 20 having inclined ridges 21 is cooled by external water troughs 23. The ashes are removed by plows 24 and fall into a hopper 25, any ash falling through the fixed grate being collected in a hopper 26, these hoppers having a common cleaning door 27. A pipe 28 supplies air or steam to below the grate and withdraws water gas during a down run. In the Specification as open to inspection under Sect. 91 (3) (a) a carburetted water gas set is also described in which the steam valve and change over gas outlet valves are inter-connected. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to automatic variable-speed gearing
IPC: F16H33/04
Filed: 1934-06-14
Abstract: 440,029. Variable-speed gearing. WICKMAN, A. C., Queen Victoria Road, Coventry. June 14, 1934, No. 17605. [Class 80 (ii)] Automatically variable gearing suitable for vehicles of the kind comprising transmission elements 17 producing rotary impulses in opposite directions alternately is provided with a one-way clutch 27 between the driving and driven shafts responsive to overrunning of the latter so that the engine can be used as a brake. Rotation of the driving-shaft 10 causes centrifugal masses 17 to be carried round over eccentrics 15 rigid with an intermediate shaft 13 so as to impart alternating rotary impulses thereto. In the form shown, there is an abutment sleeve 20 and detent rollers 24 which render backward impulses of the shaft 13 ineffective, and one-way clutch rollers 25 inside a driven drum 23 which cause the forward impulses to drive the drum continuously. The drum 23 is rigid with a driven shaft 12. The one-way clutch 27 is supported on an extension 14 of the driving-shaft 10 and coacts with a barrel 28 with a dog-clutch end 30 adapted to engage the clutch end 31 of a connector 38 which is permanently connected to the drum 23 through a yielding plate clutch 36. When the shaft 12 starts to overrun, torque is transmitted from the drum 23 to the barrel 28 whereupon the clutch 27 picks up and transmits torque to the engine which has a braking action. The plate clutch 36 yields on overload. The oneway clutch 27 can be disabled by disengaging the dogs 30, 31 by turning a pin 39 with a crank end 40. The detent 24 and one-way drive clutch 25 are, in the arrangement shown, reversible to reverse the direction of rotation of the driven shaft. The invention applies to arrangements in which the backwardimpulses are converted into forward ones.

In a mechanical contact rectifying circuit which may comprise a three-phase transformer 1 supplying load 3 through a smoothing choke 4 and main contacts 2, each of which has in series with it a smoothing choke 7, an auxiliary arc rectifier 5 capable of withstanding high overloads in series with a source 6 of auxiliary voltage, is connected in parallel with each con. tact 2 and associated choke 7. The auxiliary rectifier 5 is made conducting towards the end of each half cycle of current through that phase, and the main current is carried by the auxiliary rectifier 5 for 5-10 electrical degrees, the auxiliary voltage source 6 supplying the voltage drop across rectifier 5 and a small additional voltage which is developed across the switching chokes by the main transformer windings in the absence of the parallel circuit, so that the choke 7 can be wound for a much lower voltage. The auxiliary voltages may be derived from tappings on transformer 1 and when the auxiliary rectifiers are ignitrons as shown, the igniting voltages may be taken from additional contacts on the main switches. With this arrangement, the duration of contact of switches 2 may remain constant whatever the setting of contact closure time for determining the output voltage.
